Is XLPE UV resistant?
The material has good water and excellent chemical and oil resistance and exhibits good aging characteristics compared to PVC, except in direct sunlight. This is because XLPE's ultraviolet properties aren't as good as PVC. XLPE wires used outdoors should have a UV-resistant jacket.
What are the benefits of XLPE? XLPE insulation performs at both high and low temperatures. Due to its structure, XLPE is extremely resistant to abrasion and other wear and tear. It also boasts resistance to high voltage electricity, chemicals, and other hazardous materials.
a. IS 7098 Part 2 : 1985 XLPE insulated PVC sheathed cables For working voltages from 3.3 kV up to and including 33 kV.
XLPE provides greater tensile strength, elongation and impact resistances compared with PVC. This cross linking process also enhances the material's resistance to oil and chemicals even at elevated temperature; this makes XLPE a popular pick as insulation for LSZH Flame Retardant or Fire Resistant cables.
Carbon Black; this absorbs the UV rays to prevent damage to the polymer structure. A cable is regarded as fully UV stable when it contains 2% carbon black, although in practice 0.5% is sufficient to effectively protect the cable sheath. The addition of carbon black at these levels renders the cable black in colour.
This means that the cable is halogen-free and suitable for areas where people are present, as in the event of a fire no corrosive vapours escape from the plastic. The material is also UV and weather-resistant, water-resistant and flexible at low temperatures.
XLPE insulated wire and cable has obvious advantages, but also has some disadvantages of its own, which limits its use: Poor heat resistance and adhesion. Overvoltage can easily cause the mutual adhesion between wires, which can seriously cause the insulation to break into short circuit. Poor heat transfer resistance.
Yes, XLPE cables are water and moisture resistant. These cables also have good resistance to chemicals, salinity of groundwater, oils and corrosive furnes. Therefore, these cables enjoy wide acceptance across many industries.
XLPE is an acronym for cross linked polyethylene. XLPE is a thermosetting polymer meaning that the material (polyethylene (PE)) is cured under heat and in that process forms bonds in all directions forming a three dimensional matrix. Within this XLPE matrix there is space between the individual molecules.
PVC insulated cables has a maximum working temperature of 70°C whereas XLPE has a maximum working temperature of 90°C.
What is the maximum voltage that XLPE cables can with stand Mcq?
XLPE cable is made suitable for high voltage and extra high voltage application puto 132 kV.
Cross Linked Polyethylene (XLPE) was invented in 1963, in the General Electric Research Laboratory, to create a crosslinked material with better mechanical and thermal properties than Polyethylene, which can stand an operating temperature of 90 °C [1].
First look at the cable sheath if in the marking legend it bears a mark V90 then the insulation is PVC if it bears the mark X-90 it is XLPE, these being the Australian standard codes for such insulations.
These XLPE/PVC/AWA/PVC, XLPE/PVC/SWA/PVC, XLPE/LSZH/AWA//LSZH and XLPE/LSZH/SWA/LSZH are all available with a voltage rating of 3.8/6.6kV, 6.35/11kV and 19/33kV. The armoured power cables are commonly used for the supply of mains electricity both in aerial power networks and in underground systems.
XLPE Insulated Power Cable
XLPE is a new type of environmentally friendly product with high-temperature resistance and environmental resistance. It is made of the thermosetting plastic.
Carbon black is a major contributor to UV resistance of ties, and their longevity in the sun is dependent on the amount of carbon black used. So while using black cable ties for solar is the right way to go, the amount of carbon black really determines the ties' lifespan.
These black NYY cables have a UV-stabilised outersheath making them suitable for direct exposure to sunlight. They have an operating temperature range of -15oC to +70oC when fixed and -5oC to +50oC when flexed.
Standard PVC cables can only withstand a temperature down to -20°, whereas outdoor rated cables use a PE (Polyethylene) jacket that can withstand temperatures down to -40°C. A cable with an outdoor-rated PE (Polyethylene) jacket is recommended for cables that are going to be used in colder climates.
All cable ties are commercial grade, UL approved nylon 66, and UV resistant to ensure maximum strength and durability.
Cables are usually black in colour and are UV resistant, although this should be confirmed against individual technical datasheets if specifically required or in a location where cables are subject to elevated solar temperatures.
Is flex cable UV resistant?
The insulated rubber cable is flexible and, as well as being waterproof, it's also UV-resistant and can cope with a range of temperatures from -20°C to 60°C – perfect for all sorts of outdoor conditions.
Suitable for direct burial. Used for secondary distribution and underground service at 600 V or less. May be used in ducts or direct burial.
XLPE used in cable applications is one of the cleanest materials to recycle and can be blended with various types of recyclates and virgin materials, including Polyethylene (PE) and Polypropylene (PP).
XHHW Wire Overview
XHHW is an alphabetism or initialism which stands for "XLPE (cross-linked polyethylene) High Heat-resistant Water-resistant." XHHW is a designation for a specific insulation material, temperature rating, and condition of use (suitable for wet locations) for electrical wire and cable.
In addition to their improved chemical properties which is responsible for their amazing moisture, chemical and oil resistance, XLPE insulated cables also possess astounding mechanical properties including but not limited to impact resistance, elongation, and of course, elevated tensile strength.
Product Details. Flexible single core cables, low smoke zero halogen, low toxic and corrosive emission, flame retardant; Suitble for mains. Independently tested and certified to IEC 60332-3 and BS6387.
XLPE Cable Advantages:
Does not contain chlorine nor release toxic gases. Halogen-free.
Both linear polyethylene and XLPE tanks are made with heated resins to create a cured plastic. However, the differences in their production create very different polyethylenes with very different structural strength. Cross-linking is simply the formation of bonds between the polymer chains.
For example, XLPO is often referenced as a wire insulation when in fact XLPO is actually a broad category of different polymers. For example, “Flexible XLPO” is sometimes referenced along with “XLPE”. From a material standpoint, XLPE is a type of XLPO. Flexibility is derived from the specific polymer formulation.
XLPE wire is a single-stranded copper conductor wire that is insulated with hydronic tubing made of cross-linked polyethylene plastic (XLPE). The XLPE insulation has a three-dimensional bond within the plastic. The insulation is a thermoset, zero halogen insulation that provides flame retardant properties.

XLPE is a new type of environmentally friendly product with high-temperature resistance and environmental resistance. It is made of the thermosetting plastic.
With the increase of temperature, the characteristic peaks shift to small degree slightly, and the area corresponding to the amorphous phase (18°–19°) increases gradually. XLPE shows no obvious crystallization peak at 130 °C, indicating that XLPE has completely melted at this temperature.
